My PC is RESTARTED after 10-20 minutes playing a movie !!!

[chompi]

Hi,

Very strange. I load the movie and subs. No problem. Starts playing, no problem, very fluent video. After 10-20 minutes, my PC is restarted. It doesn't even freezes, just restarted.

BSPlayer worked just fine for a couple of months, then had this problem. Is there any background WinXP process that may be interefering with the program ?

Comments welcome.

JP.

P.S.: Using DirectX 8, DivX 5.0 ProCodec.
